tendency ofthe heat-up ytype thermal timer. portion of the residual heat yacduiured by one -thermally yresponsive `elenfient during its timing Patented June 9, 1953 UNITED OFFICE 'ELECTRIC TOASTER LudwgJ. Fichten Rockford, Ill., assigner to The :Hoover Company, NorthGanton,hio, a` corporation of Ohio 13 Claims.

V"TI-'his'invention relatesto toasters and more particularly to a thermal timer for a toaster for timing the duration of successive toasting intervalswhereby toast may be prepared done exactly asdesired regardless of the number of toasting opera-tions initiated in rapid succession or of thesetting of the manual adjustment for adjusting the toaster for making light, medium, or dark toast.

Thermal timers of the heat-up type which time the duration of toasting intervals bythe time:r it takesa thermal element'to heat up to a predetermined temperature are known in the art. However, such timers have the inherent defectthat they lmust be cooled again before a second toasting operation can be initiated. This requires the operator to wait until the thermal element has'cooled before initiating, a succeeding toasting operation or in the provision of some means for quickly cooling the thermally responsive element.

Thermal timers of the heat-up type also have the inherent defect that they tendto over-compensate. As the toaster is operated in rapid succession the toaster as .a whole acquires more andmore residual heat. This heat added to the heat of the main heaters toasts the bread faster and faster so that it is necessary to decrease the length of the toasting intervals after the rst when .the toaster is operated in rapid suces- Kproperly for timing a succeeding toasting operation. This avoids the necessity' for the operator .to wait for the thermally responsive element to cooland the necessity for providing some means for quickly cooling the thermally responsive element. It also remedies the overcompensation A operation is dissipated while it is being cooled'so that it vwill be conditioned properly for timing a succeeding toasting operation* While it is physically-impractical to cool the thermally responsive element to its original cold temperature inthe time; a'l'lowedpsufcient residualA heatv is .dissipated to just 'compensate for the residual heat Fac quiredy by` the toasterA asl a yWhole to.` shorten'each succeeding'V toasting .operation after-thel `rirst the correct amount to prepare toast of the/same. color regardless of thenumber of timesithe-toasteri is operated in rapid succession.

More'specically, according to this invention, the thermally responsive elements themselves yact as a partA of the mechanism for latchingtthe toast i'carriers in toasting position. When Athe toastcarriersmove upwardly the thermallyrresponsive element `which has justacted as'the timer ismoved awayfrom the heater so r'lthat it/will;` immediately start to cool. Additionally, the thermally responsive element which is to perform the next toasting opera-tion is not moved intdheat :exchange relationship with theheater 4until'the carriers are again movedto-toasting position. This will prevent the thermally .re sponsive element from being pre-heated by the residual heat/ofy the heaters. Further, `according to .thiszinvention the indexing mechanism :actuated by up and down movementof the r-toast lcarriers-also forms a portion of the Amechanism forlatching the toast carriers in toastingfposrtion.

.According to `another feature of thisI invention a shield is manually moved so Aas to partially shield vthe thermally "responsive element from receiving heat from the heaters soV as to adjust the timer for making light, medium, `or dark toast.

According to aimodied-formof this :invention A'an auxiliary Iheater is provided for-theiactive thermally responsive element Whichis energized simultaneously with the main heaters.

rIn this modification, when the carriers are freleased formovementto receiving position a prop- `erly conditioned thermally 'responsive element is moved into .operative position but ka shield carried 'by the toast `carriers 4is automatically Vpositioned between the thermally responsive eleyinentfan'd ythe auxiliary heater `to :prevent ythe thermally 'responsive element from being preheated by the residual heat of the auxiliary vheater. Alsol according to the modified formof the invention' the heater is: manually `.moved toward and away from the thermally 'responsive element in adjusting for light, medium,'orfdark toast.

@ther objects and Aadvantagesof "this invention will become'apparent `as the description proceeds when taken in connection fvvith the yaccompanying ldrawings in which:

Referring to the drawings the reference numeral I3 represents a base for the toaster of this invention. Supported on a peripheral ledge I I of base i3 is the lower edge of an appearance housing I2 having bread receiving slots I3 in its top. Supported on a second peripheral ledge I4 inwardly of the ledge II is a supporting plate I5 which supports the entire mechanism within the appearance housing I2.

Rigidly secured at their lower ends to the supporting plate I5 and extending vertically upwardly therefrom are a pair of guide rods I6 for guiding a carriage plate I'I for vertical reciprocation in a manner well known in the art. At their upper ends the rods I5 are secured by bracket I9 to a partition I8 which divides the interior of the toaster into a mechanism compartment and a toasting oven.

Struck rearwardly from the carriage plate Il' are a pair of arms to which are attached the bread carriers EI lying immediately below the bread receiving slots I3 in the appearance housing I2. Positioned on opposite sides of the bread carriers El in a manner well known in the art are heaters which are adapted to be energized by an on-of switch 23. The switch 23 is nominally open and is adapted to be closed by depressing a plunger 24 adapted to be actuated by a cam lug 25 extending rearwardly from the carriage plate Il, as the carriage plate I'I is moved to downward position.

Extending outwardly and rearwardly from the upper edge of the carriage plate Il are a pair of arms 23 to which are pivoted the upper ends of a pair of links 2'1, the lower ends of which are pivoted to a pair of manipulating arms 28.

At their rear ends the manipulating arms 28 are pivoted to the side walls or the toasting oven and at their forward ends, at 30, they are extended through a vertical slot 30' in the appearance housing IZ. A manipulating handle 3I is attached to the forward extensions 3U exteriorly of the appearance housing I2.

The arms 28, carriage plate I'I, the bread carriers ZI are biased to upward or receiving position by a spring 32 anchored at its upper end to a hook 33 on bracket I9 and at its lower end to hooks 34 on the forward extensions 3II of the manipulating arms 28. The partition I8 is provided with a pair of vertically extending slots 35 and 35 for the vertical reciprocation of the arms 2t' and 23 respectively.

Supported by the supporting plate I5 and extending upwardly therefrom are a pair of brackets 3l. At their upper ends the brackets 31 rotatably support a shaft 38 to which is rigidly attached the inner ends of a pair of bimetallic elements 39. Also rigid with the shaft 38 are a pair of indexing ratchets 4l] and 4| each having a pair of abutments 42 and 43 respectively. The abutments 42 are spaced 180 degrees from each other on the periphery of ratchet 4G and the abutments 43 are spaced 180 degrees from each other on the periphery of ratchet 4I and offset 90 degrees from the abutments 42.

Extending rearwardly and then forwardly in a reverse bend from the carriage plate I'I so as to clear the inner bracket 3I is a member' 44 which pivotally carries the upper ends of a pair of indexing pawls 45 and 49, the lower ends of which are biased toward each other by a spring 41. The indexing pawl 45 has an inturned end 48 and the indexing pawl 46 has a hook 49 which cooperate with the abutinents 42 and 43 respectively as will be explained presently.

Pivotally mounted on lugs extending downwardly from the supporting plate I5 is a latch lover 53 which is spring-biased to latching position by a spring 5|. The lever 50 has a toe 52 which engages the underside of the supporting plate I5 to form a stop to hold the latch 50 in its proper position to cooperate with the active bimetallio clement 39 as Will be explained hereinafter. At its upper end the latch 50 has a hook 53 which engages over the upper edge of the active bimetal 39 to latch the carriage plate Il in toasting position. The latch 5U is adapted to be rotated clockwise as viewed in Fig. 2 by a shaft 54 which pivotally supports the latch and extends through the front of the base IU where a knob 55, shown in Fig. 3, is attached thereto.

A shield 55 is pivotally supported on the partit-ion I8 at 51 and is spring-biased counter-clockwise as Viewed in Fig. l by a spring 58. A heat resisting ltransmission cord 59 is attached to thc shield 56 at 60. The cord 59 extends downwardly through an opening IBI in the supporting plate Iii and then forwardly through a guide 62 to a drum 53 rotatably mounted by a shaft 54 extending through the front of the base IU and carrying a manipulating knob 65 exteriorly of the base III.

Operation of Figures 1, 2, and 3 Bread is inserted through the slots I3 so as to rest upon the carriers 2I. The manipulating handle 3I is moved downwardly so as to move carriage plate II downwardly and position the bread carriers between the heaters 22. This will cause the cam 25 to engage the plunger 24 and close the switch 23 so as to energize the heaters 7.2.

As will become evident the bimetallic elements 39 are always positioned in a vertical position when the carriage plate II is in its upward position. Upon movement of the carriage plate I1 downwardly the end 48 of the indexing pawl 45 will engage one abutment 42 of indexing ratchet 40 and rotate the indexing ratchet 900 to position the bimetallic elements 39 in a horizontally extending position. This will move one of the bimetallic elements 39 to a position adjacent one of the heaters 22 and beneath the hook 53 of the latch 50. The same movement will cause the hook 49 of the indexing pawl 4G to engage beneath one of the abutments 43 of the indexing ratchet 4 I.

Upon release of the manipulating handle 3| the spring 32 will tend to move the carriage plate I'I upwardly. This will cause the hook 49 of the indexing link 4G to tend to rotate the shaft 38 counter-clockwise as viewed in Fig. l. However, the active bimetallic element 39 is positioned below the hook 53 of the latch 50 and will prevent countenclockwise nrovement'of vthe shaft Sit. rrhus, sincetheindexingzpawl 46 is carried by the carriage plate "H, thefcarriageplate Il 1vill he latched in its downwardposition.

From the foregoing it is to he noted that the active birnetallic element 3S and the indexing mechanism in the forni of the indexing pawli forni a part of the mechanism for latching the carriage plate il in downwardposition.

Heat from the heaters 22 will perform fthe toasting 'function and will also heat the Iactive hilnetallic element Si?. By thetinie theloreadhas heen properly toasted to the desired degree lthe estive bimetallic element'ti vwill' have been heated sulliciently to cause its 'free end to flex to the left as viewed in. Fie. 2 until it moves from beneath "le hoch of the latch Aand 'free thecar iiage plate il for upward movement under the hias of the spring 32.

Upward movement of the carriage plate il' and oorrespondingly the indexing paivl a6 'ivill rotate the Ishalt 33 counter-clockwise as viewed in Fig. l. to position the hiinetallic elements 39 in vertically extending position. It is to be noted that that mot-'ement will move the active bimetallic element Sil out of heatexchange relationship with the heaters 22 but will not movethe inactive hinietallic element il@ into heat exchange relationship with the heaters 22 so that the inactive biinetallic element will not be preheated and the active hiinetallic element 39 will immediately heein to cool.

A second toasting operation may be immediately initiated by inserting new slices and moving the manipulating handle 3| downwardly as before. rEhe previously inactive biinetallc element will now he moved into heat exchange relationship with the heaters 22 `ley engagement of end ./ll of the indexing pawl with. one of the ahutrnents as previously described.

During the ilrst toastineoperation the toaster a whole acquired residual heat so that the toast will he prepared faster than for the rst toasting operation. However, the inactive bimetaliic element 39 will also have acquired some residual heat upon beine heated by the heaters 22 will warn and move from beneath the hook 53 to release the carriage plate i "i soonerthan for the :lirst toasting operation so as to compensate for 'the added residual heat acquired by the'toaster as a vhole.

The loiinetallic element 3! which previously acted as the timer is being cooled 'during this iod. li a third toasting operation is immediately begun, after the termination of the second, the operation will he the saine as before rexcept that the inactive biroetallic element 3S during the second toasting operation will not be cooled to low a temperature as it was originally starting with a cold toaster but will have acquired some residual heat. This residual heat will be just sufficient to terminate 'the third'toasting operation faster than the second sulcient to con'ipena for the added residual heat acquiredby t e toaster as a whole. However, since the bimetallic elements are cooled between operative periods suilicient residual heat will he dissipated from the hiinetallic elements Siti to prevent them from operating too rast. By proper design it rhas been found that the heat d by the thermal responsive elements 39 duri inactive periods will prevent ova-compensation vof the bimetallic elements. That is, the timer will operate faster for the third toasting operation than for the second but not'sufciently fast Ato operate the latch ment of carriage plate il to initiate a suecee.A `toasting operation end 48 of the indexing will engage the release mechanism `before lthe 'toast properly.

If dark toast is desired the knob (i5-is rotated to wind moreofthe cord '-59 onthe drum 63 sovas topivot'the `shield 56 clockwise as viewed in Fie. l and Inove the shield 5S between the heaters 22 -andthe activebilnetallic element 39. It will then takelonger for the'factive bimetallic element Seto reach `its lreleasing position with the result that 'clark toast willfbeprepared.

if light or medium toast is ldesired the imola t5 yis rotated in the opposite .direction whereby the spring 5B will pivot the shield counterclockwise-and expose more of the active bimetallic element '39 to the'heat radiatedfrom the heaters 22 2to heatthe active bimet'allicelement 39 faster and shorten the toasting period so that light or medium toast willresult. f

If Aat any time itis desired to stop the toasting operation it is only necessary to rotate the'knob 55 clockwise, vas viewed in Fig. 3, to move the hook E3 from above the upper edge of the active birnetallicelement '39 `and the carriers will move to receiving position as previously described.

Referring to the modification of Fig. 4,-where the parts are the same as in the .inodincation of Fiss. l to 3, inclusive, they have been given the same reference numerals. The parts which are the same as in the modification of Figs. 1 to inclusive, have not been redescribed but only the modified construction.

This'rnodiiication differs over that of the modiiication oi Figs. l toS, inclusive. in that the shaft fit? carries three bimetallic elements (i6 spaced .lflo about the shaft 38 and a single indexing ratchet Fil' having three abutments il@ also spaced o about the Ipin 38 and in radial alignment with the birnetallic elements 66.

A modified shield is pivotally supported on pedestal 1t, extending upwardly from the sup portine plate i5, by a pin il about which the cord 59 is wrapped so that when the knob is rotated the pin il andshield iii-l are rotated to shield more or less of the active bimetallic element 56 from the heat of the heaters 22 the same as in the modification of Figs. 1 to 3, inelusive.

The operation of this modification is substauM tially the same as that of the modification of l. to 3, inclusive. except that upon upward movement of the carriage plate il the hook MJ is ,dorre `of the indexing pawl 4s will engage one of the ahutinents '558 to rota-te the pin. '33 approximately 30 `or to a position where the abutment @t is positioned below the end A8 oi indexing pawl That will move the previously active bimetallio velement (it .from heat exchange relationship with the heaters 2.2 but will move neither or the previously inactive oin'letallic elements to into exchanee relationship with the heaters At this ti e the heaters More deenergized and vv. .le some residual heat will he transmitted to toe previously inactive biinetallic element lii this vez l not heinaterial because upon downward move-- ,se-abutment and ro* the shaft 35i approximately 90 to :nove conipletely reconditioned bimetallic element te into operative or active position with its :free end en gaged 'oeneath'the hook 53 of latch In the modification oi Figs. 5 to 7, inclusive,

'the toaster .issubstantially the t at oi thernodication of'Figs. 1 tc, inclusive. llhere 'fthe kparts arefthefsamefthey have been given the saine reference characters as in Figs. 1 to 3, inclusive, and only the modified construction will be described.

In this modification, the carriage plate l1, near its lower end. is provided with outwardly and rearwardly extending arms 12. The lower ends of links 13 are pivoted to the rearwardly extending ends of the arms 12 and at their upper ends the links 13 are pivoted to the manipulating arms 28. The edge of the carriage plate I1 has a cam 14 to contact the plunger 24 and close the switch 23 when the carriage plate I1 is moved downwaidly.

Extending upwardly .from the supporting plate l are a pair of standards 15 which rotatably support a shaft at their upper ends. Rigidly attached to the shaft 1G are a pair of bimetallic elements 11 spaced 180 and normally positioned in a horizontally extending position. Also rigidly attached to the shaft 16 is a ratchet wheel i8 which cooperates with a pinion 19 by means of a pawl Attached to the front of the carriage plate i1 is a rack 8| which cooperates with the pinion 'i9 in a manner to be described.

Pivoted to lugs extending downwardly from the supporting plate l5 is a latch lever 82, having a hook adapted to overlie the upper edge of and an abutment 83 adapted to engage the underside of one of the bimetallic elements 11 in a manner to be hereinafter described. The lever 82 is biased clockwise as viewed in Fig. 6 by a spring 8f;- which causes the toe 85 of the latch 82 to engage the underside of the supporting plate i5 so that the latch 82 will return to latching position. The latch 82 may be moved counter-clockwise to manually release the carriers for upward movement by a knob 8f3 attached to the latch 7E" by a rod 81 extending forwardly through the front of the base IS.

An auxiliary heater 88 connected in series with. the main heaters 22 is carried by a reflector' 8S positioned immediately in front of one of the bimetallic eleznents 11. The reflector 89 and the auxiliary heater 88 are carried by a lever 90 pivoted intermediate its ends at Si to the supporting plate l5. A knob 92 positioned exteriorly of the front of the base lil is rigidly attached to the shaft 93 screw threaded through the front of the base i8. The inner end of the shaft 93 is rotatably attached to the lower end of the lever Si) in any suitable manner such as by the nuts as shown in Fig. 6. Secured to the carriage plate il' and positioned so to lie between the heater 83 and one of the bimetallic elements 11 when the carriage plate l1 is in upward position is a shield 94. The surface of the shield S4 facing the heater 88 may be made reflective so that the shield Gil will not readily absorb heat from the heater 88.

Operation of the modification. of Figures 5 to 7, inclusive Bread is inserted through the openings I3 and the manipulating handle 3l is moved downwardly as in the first modication. This will cause the cam 'le to engage the plunger 24 of switch 23 to close the switch 23 and simultaneously energize the main heaters 22 and the auxiliary heater 88. rThe teeth of the rack Si will engage the teeth of the pinion 13 and rotate it clockwise. However, the pawl Bil will merely ride over the teeth of the ratchet i3 so that the shaft 16 will remain stationary and the ibimetallic elements 11 will remain in horizontal position. The hook 83 of the latch 82 holds the bimetallic elements 11 in their horizontal position during this movement.

When the manipulating handle 3| is released the spring 32 will tend to move the carriage plate l1 upwardly but since the pawl 80 will engage with the teeth of the ratchet 18 and the shaft 16 is held against counter-clockwise rotation by the abutment 83 engaging one of the bimetallic elements 11 the carriage plate I1 will be latched in its lowered position.

Heat from the main heaters 22 will perform the toasting function and heat from the auxiliary heater 88 will be transmitted to the active bimetallic element 11 and cause it to slowly flex toward the right as viewed in Fig. 5. By the time the main heaters have performed the toasting function the free end of the active bimetallic element 11 will have moved out of engagement with the abutment 83 so that the carriage plate l1 will move upwardly under the bias of the spring 32.

Movement of the carriage plate l1 to upper position comes about by reason of the fact that movement of the free end of the bimetallic element 11 from above the abutment 83 will permit the shaft 16 to be rotated freely by the action of the rack 8|, pinion 19 and pawl 80 until the free end of the previously inactive bimetallic element 11 engages the abutment 83 of latch lever 82 which will arrest further upward movement of the carriage plate I1.

Upward movement of the carriage plate I1 will cause the shield 94 to be moved between the auxiliary heater 88 and the free end of the cool bimetallic element 11 so that residual heat from the` auxiliary heater 88 will not be transmitted to the cool bimetal 11.

A second toasting operation may be immediately initiated by inserting new slices of bread through the openings I3 and again moving the manipulating handle 3| to downward position as before. The operation will be the same as for the first toasting operation except that the previously inactive bimetallic element 11 will have acquired some residual heat from the main heaters so that it will be heated quicker by the auxiliary heater 88 and moved to its releasing position sooner than for the first toasting operation. The residual heat acquired by the inactive bimetallic element 11 during the first toasting operation will be just sufficient to compensate for the residual heat acquired by the toaster as a whole so that for the second toasting operation the toast will be done to the same degree of brownness as for the rst.

During the second toasting operation the previously active bimetallic element 11 is being cooled to recondition it for a succeeding timing operation. If a third toasting operation is initiated immediately after the first the operation will be the same as before except that the bimetallic element 11 which was active for the nrst toasting operation will not be cooled to its original `cold condition and will therefore terminate the third toasting operation faster than the second. Again this will tend to compensate for the additional residual heat acquired by the toaster as a whole and for the third toasting operation the toast will be done to the same degree of brownness as for the first and second.

If dark toast is desired the knob 92 will be rotated to pivot thc lever 90 so as to move the reflector and auxiliary heater 88 farther away from the active bimetallic element 11 so that it will take a longer time for the auxiliary heater to heat the bimetallic element 11 which will away from said heating means as said carriers move to receiving position, and return movement of said carriers to toasting 4position operates said indexing means to bring an inactive of said thermally responsive elements into cooperating engagement with said latch.
